IMPROVEMENT IN JOURNAL-BOX AND BEARING.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES B. CARYL, of Gander, in the county of Ticgn, and State of New'Yox-k, have invented certain new and useful improvements in Journal-Boxes and Bearings; and I do hereby declare that the following is a full, clear, and exact description thereoflrefcrence being had to the accompanying drawings, making part of this specification, and to the letters of reference marked thereon, like letters indicating like parts wherever they occur. 1

To enable others skilled in the art to construct and use my invention, I will proceed to describe it.

My invention consists in a novel manner of constructing journal-box es and arranging friction-rollers therein, in such a manner as to substitute rolling for rubbing surfaces, to decrease friction.

Figure 1 is a longitudinal section of my improved apparatus with a. journal inserted.

Figures 2, 3, 4-, and 5, are views of portions showndetached. i

It is well known that much of the power applied to machinery of all kinds is absorbed by the friction of the journals and their bearings, the surfaces of these parts rubbing or sliding on each other, where they come in contact, and that this rubbing of the parts upon eachother causes a constant wearing away of their surfaces oft-en heating, and greatly injuring them, especially when run at a high speed, and where heavy shafts and wheels are user], the weight of which tends to press out or displace the oil or other lubricating material from between the rubbing or bearing surfaces. It is also known that when surfaces-are caused to roll upon each bther, much less friction is produced than when the surfaces slide or rub one upon the other. Many plans-have been devised for applying these principles in machinery, to les'senthc friction and wcar and economize power, but so far as I am aware with but limited success. The object of my invention is to reduce the friction in such cases to the least possible amount, bv so constructing the parts as to substitute rolling for the ru bbing surfaces usually 1 employed.

To accomplish this object, I construct my journsl-bcx, B, with an interior cavity or circular chamber, considerably larger ir diameter than the journal which into have its bearing therein, as shown in section in fig. 1. I then provide a series of rollers, it, of such a diameter that when arranged in a circle, as shown. in fig. 4, they will just slip endwisc into the chamber of the box B, and fill the space surrounding the journal, as shown in fig. 1L These -rollers R are held together by journals, e, on each end, having their hearings in a ring, A, at each end, as shown in fig, which is an end view of the rollers with a ring, A, applied. The two rings A are held together by small rods, j, which. extend from one to the other, as shown in fig. 5, which is a face view of the rollers and ringsunitcd. When the rollers R are inserted within'the box B, as shown in fig. 1, it will be observed that a' small portion of their inner ends abuts against a shoulder, u, which prevents any lateral movement of as shown in fig. 1. This cap E is recessed cn itsinncr face, as shown, to leave a space between it and the end of the journal 11, and also between it and the ends of the rollers R, leaving asiiiall shoulder, u, to bear-against the outer endsof said rollers, to prevent any lateral movement of the same towards the cap E. It will be understood that the shoulders u and it, (which constitute the only rubbing surfaces in my improved deviee,)'should be made as small as possible, and answer the desired purpose, so as to reduce-the rubbing surfaces to the minimum amount. In orderto prevent the friction which mightibe caused by the lateralmovement or clay otthc shaft or journal A, I construct the inner shoulder of the box B with a groove, b, as shown in fig.1. I thensecuro to the shaft or journal A a collar 0,-hn-ving'n. similar groove, d, forn cat on its face adjoining-the box B. lthen provide a seriesof balls, D, which are arranged in a circle and held in position by being jcurnellcd in holes in a flat ring, H, as represented in figs. 2 and 3, th e former being a side and the latter an edge view of the same.

These balls D are held in the ring H by small pins or'journals, o, as shown in fig. 3; these journals 0 being sc locatcd as to bring the axis of said balls D radial, as indicated by the dottedlincs in This series of balls D being tlius arrnnged,'ar c placed between the collar G and the box B, as shown in fig. 1; the size of the balls Dand their ring H being such as to cause the balls I) to'fit in thia grooves b and d. It will thus be seen that as the shaft A with its collar C revolves t'nc balls D will simply roll in the grooves 12 andd end arevent any friction from being generated between the faces of the collar and the box,and'that thus rolling surfaces are substituted instead of rubbing surfaces at all points of the bearing, except between the ends of the rollers N" 'the' box B, thus eneloslng'aml covering the balls DI l I R and ll:BSh0llld 0-T u zzml u", as hereinbafoi'e gxplained; thus redu b'mg the nubmng surfaces to thl east'possible amon nn 'ihc inner end of the box B is fQfmalIcir'cUInn-and luis a pigcupil "entialgroovc, 11, formed thereon, as shnlvn'l'n fig. 1.
